Safety Ratings

This is where the biggest differences in system design show up. Low voltage DC is safer from shock but just as much of a fire hazard. AC electricity from inverters is safer than grid power; an inverter will shut down sooner than a breaker in many short circuit situations. But this is no excuse for shoddy wiring.

.We offer Three levels of safety : The Renegade, NEC code compliant, NEC plus


UL: Underwriters Laboratories, tests and approves equipment for safety. Most inverters, wiring, breakers, conduit, solar modules, etc. are UL listed. fuel generators, wind generators, & integrated solar packages are not UL listed.
SAE is the Society of Automotive Engineers, they provide standards for wiring of most low voltage DC systems in the US: autos & RVs. Automotive type fusing, battery cables, & batteries are usually SAE approved, but not UL listed.
NEC: National Electrical Code provides standards that most residential & commercial wiring have to meet. It has a specific section dealing with solar equipment installed in houses (article 690)NEC does not cover stand alone generators, power systems, or wind generators, only their interconnection to the house wiring. NEC recommends UL listed equipment, but does not require it. SAE is not mentioned in the NEC.
Local inspectors generally adopt the NEC, but can interpret the code very differently in different places.
NEC Code compliant vs UL approved: code compliant means the assembly uses UL listed components and is wired to meet the letter of the code. UL listed means that the entire assembly is UL approved and therefore the entire power board can not be challenged by the local inspector.

The Renegade uses a mixture of UL listed components and SAE components that an inspector might frown upon, but its still safe. The basic wiring is the same: All circuits are fused, etc. The main difference is that low voltage (12v) wiring is exposed and automotive type fuses are used. This meets or exceeds standards for vehicles, RVs, small cabins, portable systems, etc.

All our other systems are at least NEC Code Compliant . It uses UL listed components where ever appropriate, and should pass inspection. It is up to the buyer to research local code enforcement and determine local practices. Some areas adhere to strict enforcement, other areas have ignored smaller homes in remote areas. Check with neighbors who are on solar. Using this level of system will insure that it will pass even if inspected later. UL approved complete power boards available by special order. UL approval is not necessary for safety, but can help with a difficult inspector.

NEC plus lightning protection: NEC alone does not adequately address the single most common safety issue we see: Lightning. This level of safety not only includes Polyphasor lightning protection, but an advanced grounding system designed for your site, A DC Light if the inverter shuts off is also included.

NEC plus Battery Containment: if the system will be located in an interior living space, we reccomend these advances. Lead Acid Batteries emit Hydrogen Sulfide gas when charging. In small quantities it isn't noticable, but larger battery banks and charging sources can produce high enough concentrations that the gas smells like rotten eggs, is poisonous, and is flammable. The NEC has no specifics on batteries, boxes, or their venting.
WE use all acid resistant materials, special maintenance equipment, and an advanced venting system designed for your room. If the batteries are located outside of your living space in an adequately ventilated area, these extra precautions may not be necessary.
